At present, the installation of wall-piercing bushings mostly adopts manual hoisting. For high-voltage wall-piercing bushings, especially wall-piercing bushings with a voltage level of one million volts, the weight can reach 20-30t, and the installation height can reach more than 20m. It greatly increases the difficulty of installing the million-volt wall bushing, especially the angle control of the wall bushing during the hoisting process is more difficult

Embodiment Construction
[0018] The present invention is further detailed below with reference to the accompanying drawings and examples:
[0019] like Figure 1 ~ 4 A millions of millions of dried wrap sleeves shown include the following steps:
[0020] Step 1: Wireless Wall Ombry 2 is fixed in the wall 3 before the wall plate 1 is installed, and the wall hole is used to secure the wall, the wall 3 for supporting the wall sleeve 4. The wall 3 side is a synthetic hall, and the other side of the wall 3 is a oscillating hall, and the wall hole embedded member 2 is formed in the concession wall portion 2.1 is flat and fixed in the wall. 3;
[0021] Step 2: Wearing the wall plate 1 is fixed within the mounting wall 3, wherein the wall plate 1 is composed of a large waters 1.1 located within the synthetic hall 5 and a small waters 1.2 located in the oscillation hall 6, and passed the laser accuracy. The vertical meter and the horizontatometer adjust the wall of the wall to ensure the axial direction of the larg...

The invention relates to a method for installing a million-volt dry-type through-wall bushing, which includes using a bushing installation tool to fix the through-wall board, hoisting the million-volt dry-type through-wall bushing, aligning holes between the flange and the through-wall board, and nuts Fixed and other processes. The invention utilizes various installation tools to realize the fixing of the through-wall bushing through the wall plate, the hoisting of the million-volt dry-type through-wall bushing, the alignment of the flange and the through-wall plate, and the fixing of the nut, which greatly reduces the It reduces the difficulty of installing the high-altitude wall-piercing bushing, and improves the accuracy of the hole alignment between the wall-piercing bushing flange and the wall-piercing plate.
Description
Technical field [0001] The present invention belongs to the field of electricity engineering, and in particular, the present invention relates to a method of mounting a million volt drying wall sleeve. [0002] technical background [0003] The wall sleeve is used as a carrier conductor through a wall different from its potential, introducing or introducing full voltage, full current, insulation and mechanical support, collecting electricity, heat, force, chemistry, etc., is a development of transmission system. To ensure the key devices of system security and stable operation. At present, the installation of the wall sleeve uses manual hoisting mode. For the high voltage grade, the wall sleeve, especially the millions of volt pressure level, the weight is reached 20 ~ 30T, the installation height can reach more than 20m, It has greatly increased the difficulty of installation of millions of volt wall sleeves, especially the angle control of the wall sleeve during the hoisting pro...
